Dear tutor,
Please answer the quiz as fast as you can as I need to know the answer right now. No need for an explanation, just answers should be fine.

Suppose the bottom ot the ladder is sliding away trom the wall at a constant rate 012 feet per second. How fast is the top of the ladder sliding down the wall when the bottom is 3 feet away from the wall? We note that the ladder is a c length, but the the top of the ladder will s rate that the bottom of the ladder is moving away from the wall.
